BACKGROUND OF THE INVENTION

The present invention generally relates to a trashcan assembly having bag engaging members for grasping and retaining a trash bag.

The use of trashcan devices is known in the prior art. U.S. Pat. No. 6,126,031, which is incorporated herein by reference, describes a device having a bottom compartment for holding a roll of trash bags so that the trash bags may be retrieved as needed through an opening extending into the bottom compartment. Another type of trashcan device is disclosed in U.S. Pat. No. 5,636,416, which is incorporated herein by reference, which device has a conventional shape and which includes clips that are attachable to a trash bag. The clips are positioned outside of the trashcan to prevent the trash bag from falling back into the trashcan. Another clip assembly for securing a trash bag is found in U.S. Pat. No. 5,645,186, which is incorporated herein by reference.

While these devices fulfill their respective, particular objectives and requirements, it is believed that a need remains for a simple trashcan assembly that allows a trashcan liner—sometimes referred to herein as a trash bag and vice versa—to be secured directly to the trashcan assembly in order to prevent the trash bag from slipping and falling into the trashcan assembly.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.

Turning now to FIGS. 1-2, three different trashcan assemblies 200,300,400 are illustrated, which are all generally in accordance with a first aspect of the present invention.

The trashcan assemblies 200,300,400 have many features in common. For example, each trashcan assembly includes a trashcan container 202 and an attachment member 204,304,404 that is received on a rim 206 of the trashcan container 202 and that includes at least one bag engaging member 208. The attachment member 204,304,404 generally resembles a band and has an inner diameter of about fourteen inches. The attachment member 204,304,404 also includes an annular recess (visible, for example, within the attachment member 404 on the right in FIG. 2) within which the rim 206 of the trashcan container 202 is received. The rim 206 may be received in a “press-fit” or “snap-fit” connection within the attachment member 204,304,404, or may be adhered or otherwise bonded to the attachment member 204,304,404 for permanent attachment thereto.

The trashcan assemblies 200,300,400 also have differentiating features. These features relate to the circumferential side profiles of the attachment member 204,304,404 in each assembly. In this respect, the first illustrated trashcan assembly 200 includes an attachment member 204 having a generally uniform height; the second illustrated trashcan assembly 300 includes an attachment member 304 having a height that gradually varies along the circumference of the trashcan container 202; and the third illustrated trashcan assembly 400 includes an attachment member 404 having a height that sharply increases in the areas of the bag engaging members 208.

For each of the assemblies, the attachment member 204,304,404 preferably is injection molded from one or more materials. The materials preferably comprise one or more thermoplastic materials and/or one or more elastomers.

In some embodiments, the entirety of the attachment member is made from the same material, i.e., a single source material, in an injection molding process, and each bag engaging member 208 is formed by simply forming openings 212 in the attachment member, either during the injection molding process or thereafter. In other embodiments, different portions of the attachment member 204,304,404 are formed from different source materials that are co-molded together, i.e., the bag engaging members 208 are preferably formed from a material that is more resilient and/or more flexible than the material from which the remainder of the attachment member 204,304,404 is formed.

As shown herein, the openings 212 have a generally X-shaped configuration. However, it will be understood that in at least some embodiments each opening 212 may have any configuration that enables a bag engaging member 208 to grasp and retain a trash bag when a portion thereof is inserted through the bag engaging member 208.

The bag engaging members 208 of any of the three trashcan assemblies 200,300,400 may include any one of the different types of bag engaging members that are disclosed in the incorporated references, including U.S. patent application Ser. Nos. 11/424,920; 11/424,942; 11/424,968; and 11/424,969.

The containers 202 of each of the three trashcan assemblies 200,300,400 are identical. It is preferred that the container 202 comprise a porcelain coated steel member. However, the container 202 may comprise a different material such as plastic or any other material conventionally used for forming trashcan containers. As will be apparent from the exploded view of FIG. 2, “cutouts” 214 are provided about the rim 206 of the container 202 so that each bag engaging member 208 provides access through the openings 212 therein into the interior of the container 202. Each cutout 214 generally corresponds to the area of the opening 212 of a bag engaging member 208.

A trashcan assembly 500 in accordance with an embodiment of another aspect of the invention is illustrated in FIG. 3. The trashcan assembly 500 of FIG. 3 includes an outer container 502 having a hinged lid 504 as well as an interior container 506 that is removably received within the outer container 502. The outer container 502 preferably comprises a porcelain outer shell. However, the container 502 may comprise a different material such as plastic or any other material conventionally used for forming trashcan containers.

The interior container 506 includes bag engaging members 508 that register with “cutouts” 510 in the rim 512 of the container 502 when the interior container 506 is received therein, as shown in FIG. 3. Similar to the rim attachment member 204,304,404 of FIGS. 1-2, the interior container 506—including the bag engaging members 508—may be made in an injection molding process entirely from the same material, or the interior container 506—including the bag engaging members 508—may be made in an injection molding process in which portions are co-molded together, wherein the bag engaging members 508 are made from a material that is more resilient and/or more flexible than the material from which the remainder of the interior container 506 is made.

The bag engaging members 508 of the interior container 506 may include any of the different types of bag engaging members that are disclosed in U.S. patent application Ser. Nos. 11/424,920; 11/424,942; 11/424,968; and 11/424,969.

In a variation of the foregoing trashcan assemblies 200,300,400,500, the “cutouts” 214,510 in the rim 206,512 of the trashcan containers 202,502 of FIGS. 1-3 may be replaced with openings that do not extend to the top of the containers. In this variation, the top edge of the containers 202,502 thus may be continuous within a plane.

Now turning to a second aspect of the present invention and with reference to FIGS. 4-6 and 10, an insert 10 in accordance with a second aspect of the present invention is illustrated. In this regard, FIG. 4 illustrates a front perspective view of the insert 10; FIG. 5 illustrates a rear perspective view of the insert 10; and FIG. 6 illustrates a side elevational view of the insert 10.

As perhaps best seen in FIG. 6, the insert 10 includes a channel 26 that is formed in, and extends about, the periphery of the insert 10. The insert further includes a front skirt portion 28 and a rear skirt portion 30. As illustrated, the periphery of the insert 10 is generally circular, the channel 26 extends continuously about the insert 10, and the skirt portions 28,30 likewise are generally circular and extend continuously about the insert 10.

In accordance with the invention, the insert 10 includes a liner engaging member (sometimes alternatively referred to as a “liner engaging portion,” a “bag engaging member” or a “bag engaging portion”) indicated generally by 12. The liner engaging member 12 includes an arrangement of a plurality of fingers 14 that extend in a generally radial direction from a central opening or aperture 16. Together with the aperture 16, the fingers 14 define a passageway through the liner engaging member 12.

The fingers 14 further are configured to receive and retain a portion of a trash bag or liner when extended therethrough. Moreover, each finger 14 preferably is bent or curved such that the finger protracts (i.e., gently slopes) outwardly along a direction from a distal end thereof toward a proximal end thereof located at the aperture 16; and then retracts toward a rear of the liner engaging member 12 such that the terminal end or tip 24 of the finger 14 generally points toward the rear side of the liner engaging member 12 (i.e., toward the interior space of a trashcan when the liner engaging member is installed in a container as shown, for example, in FIG. 8 discussed below). The fingers 14 at their bends, i.e., at their “knuckles” 22, thereby serve to define and bound the central opening or aperture 16. As defined thereby, the aperture 16 may approximate the cross-sectional dimensions of an average human finger.

The fingers 14 themselves are defined by a plurality of slots 18 that also extend generally radially from the aperture 16. The proximal end of each slot 18 connects to the aperture 16, while each slot 18 includes a large rounded opening at its distal end that serves a venting function for release of air that otherwise may become trapped between a trashcan container 100 and a liner when the liner is first placed within the trashcan for use.

Additionally, the slots 18 as illustrated define an open space in the general shape of an “X,” wherein the ends of the open space are rounded or pear shaped. Additionally, each end of the open space in the shape of an “X” may comprise an opening that is approximately the size of the central opening 16 centrally located between all of the terminal ends of the fingers 14.

Each finger 14, of which there are four in the illustrated liner engaging member 12, preferably is resilient and flexible and returns to the position shown in FIG. 4 after being deflected or bent, such as may occur when a portion of a liner is inserted through the passageway. The insert fingers 14 are shown in FIG. 10 in deflected positions as the result of a human finger being inserted through the passageway in the direction of arrow A generally along the axis of the central opening 16. When the human finger is withdrawn, the insert fingers 14 return to the default positions as shown in FIGS. 4-6.

In a variation of the liner engaging member 12, not shown, the central opening 16 includes dimensions sufficient to receive therein a person's finger without displacement of the insert fingers 14. In such variation, the fingers 14 provide sufficient friction with a liner inserted through the passageway so as to keep the liner from slipping into a container during use. Sufficient friction is provided by both the coefficient of friction of the material used to form the fingers 14 and the surface area of the fingers 14 that is in contact with the liner. In this latter respect, the bending of the fingers 14 and their rearward extension (which would be toward the interior space of a container) increases the surface area of the fingers 14 that is in contact with the liner compared to fingers lacking such bend and rearward extension.

In another variation of the liner engaging member 12, not shown, the slots 18 (but not the central aperture 16) are replaced by areas of reduced thickness sections or walls and are formed from an elastic material such that the fingers 14 are movable and bendable relative to one another. In such alternative, these elastic areas are more easily stretched and deformed than the fingers 14. These elastic areas further may include openings that serve the venting function of the slots 18 of the liner engaging member 12.

In still other variations, the actual arrangement of the fingers 14 and the three dimensional contours thereof (i.e., the gradual sloping and then bending, etc.) may vary within the scope of the present aspect. Moreover, in some embodiments, the fingers of the liner engaging member may be generally coplanar with the insert and aligned with a section of a peripheral wall of a container and, thus, not include portions thereof protracting to any substantial extent beyond the bounds of the planes of the skirt portions of the insert. In such variations, the fingers would not protract outside of the planes of the skirt portions but, nevertheless, could still include bending with finger tips pointed rearward. Moreover, for example, the fingers could be “L” shaped, “J” shaped, or “T” shaped while still existing within the bounds of the planes of the skirt portions of the insert. In accordance with certain additional embodiments of this aspect of the invention, any one of the different arrangements of fingers may be used as disclosed, for example, in the incorporated references, including U.S. patent application Ser. Nos. 11/424,920; 11/424,942; 11/424,968; 11/424,969; 60/891,931; 11/778,839; and 11/778,841; U.S. Pat. No. 7,243,811; and U.S. Patent Application Publication No. 2007/0034334 A1.

With particular reference now to FIGS. 7-9, installation of inserts 108,110 in a trashcan container 100—and the resulting trashcan assembly formed thereby—are described in detail. The inserts may be installed during manufacture of the container or during retrofitting of a conventional trashcan container.

In this respect, a trashcan container 100 is illustrated in FIG. 7. As shown therein, two openings 104 have been cut, punched, stamped, or otherwise formed in the wall 102 that forms the sides of the container 100. The openings 104 are illustrated as generally circular, but the invention is not limited to circular openings and, as will be apparent to the Ordinary Artisan, any other profile may be utilized as desired. The trashcan container 100 also may include a different arrangement and number of openings other than the two opposed openings 104 illustrated in FIGS. 7-9, as desired.

The inserts 108,110 are identical to one another, and each has a similar circular profile as each of the openings 104. Additionally, each insert 108,100 is substantially the same as the insert 10 of FIGS. 4-6 and 10 and, as such, a detailed description of each insert 108,110 is not included herein other than to acknowledge with reference to FIG. 9 that each insert 108,110 includes resilient bent fingers 114 having knuckles 122; a central opening or aperture 116 bounded by the knuckles 122; a front skirt 128; and a rear skirt 130.

Each insert 108,110 is installed in the wall 102 of the container 100 by forcing the insert 108,110 into a respective opening 104 such that the section of the wall 102 defining the respective opening 104 is received within the channel of the respective insert. Such disposition of inserts 108,110 is illustrated in FIG. 8. An insert 108,110 may be forced into an opening 104 in a direction from outside to inside of the container 100 but, preferably, such insert is forced into the opening 104 in a direction from inside to outside of the container. Such forcible seating causes deformation of at least a portion the insert but, due to the resilient nature of the insert, the insert quickly recovers upon its seating within the opening 104. Additionally, when properly seated in the opening 104, the front skirt 128 bounds the opening on the exterior surface of the wall 102 of the container 100, and the rear skirt 130 bounds the opening on the interior surface of the wall 102 of the container 100. When installed in the container 100, each insert 108,110 defines a passageway into the interior space of the trashcan container for receipt therethrough and retention therein of a portion of a trashcan liner.

In variations of the container 100, not shown, the container may have a round shaped periphery or an elliptical shaped periphery rather than a generally rectangular shaped periphery like container 100. An insert 108,110 may be placed into an opening of a container of any shape in the same way as described for container 100. In a further variation of this aspect of the invention, the shape of the insert may mimic the shape of the container. For example, for an elliptically shaped container, the insert may also be elliptically shaped.

The insert may be manufactured from a resilient, rubber-like or plastic material and may constitute a single piece. The insert also may be received within the opening of the peripheral wall in a “press-fit” or “snap-fit” connection and, optionally, may be adhered or otherwise bonded for permanent attachment to the wall.

Based on the foregoing description, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention.

Accordingly, while the present invention has been described herein in detail in relation to one or more preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purpose of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications or equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.
